Returns the sequence of all ICmp predicates.

Returns the sequence of all FCmp predicates.

Return an estimate for the code size reduction (in bytes) which will be caused by removing the given branch instruction during if-conversion.

These two forms are equivalent: sub %y, (xor %x, -1) add (add %x, 1), %y The variant with two add's is IR-canonical. Some targets may prefer one to th

Return true if the heuristic to prefer icmp eq zero should be used in code gen prepare.

This callback is used to prepare for a volatile or atomic load. It takes a chain node as input and returns the chain for the load itself. Having a ca

Return true if the checker's analysis was not abandoned, i.e. it was not explicitly invalidated. Even if the analysis is not explicitly preserved, if

Returns true if MI's Def is NullValueReg, and the MI does not change the Zero value. i.e. cases such as rax = shr rax, X where NullValueReg = rax. Not

Print binary ids on stream OS.

Implement target specific printing of target custom pseudo source value. Default implementation is not necessarily the correct MIR serialization forma

Implement target specific printing for machine operand immediate value, so that we can have more meaningful mnemonic than a 64-bit integer. Passing No
